Nuclear expert: Powerful explosion at reactor No. 3 may have been from “prompt criticality” in spent fuel pool (VIDEO)
Gundersen Postulates Unit 3 Explosion May Have Been Prompt Criticality in Fuel Pool, Fairewinds Associates, April 26th, 2011:
When building 3 of the Fukushima Daiichi plant exploded last month, those who saw the video footage were left to wonder why it was more severe than the other explosions. Adding to the mystery were reports that the containment and reactor in building 3 were still intact. Gundersen discusses several known facts about Fukushima 3 and theorizes on a possible scenario leading to the explosion.
